Abstract

A golf club is disclosed herein having aerodynamic characteristics reducing drag resistance to maintain maximum head speed which includes a head having a front face with a top surface and an undersurface rearwardly sloping together to define a tapered back face. The sides of the head slope in convergence from the top surface to the undersurface. A pair of open-ended arcuate passageways are provided in the head substantially in parallel with a round opening at the front face and terminating in an oval exit at the back face. The radius of the arcuate passageways lies on the radius of the golfer's swing and a pointer is located on the top surface adjacent the front face to indicate alignment with sweet spot location on the front face. The undersurface includes a pair of ridges defining a central groove and opposite side grooves with terminations at the oval exits of the passageways.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A golf club head comprising: a body having weighted mass with a front face, a back end, opposite sides connecting said front face with said back end;   said body further having a top surface and an undersurface joining with said back end;   a pair of arcuate open-ended passageways provided in said body having a central curved axis following the arcuate swing of the golf club head;   one open end of each of said passageways being shaped as a circular opening with an opposite open end of each of said passageways being shaped as an oval opening;   said body undersurface being provided with a pair of spaced-apart ridges separated by a central groove and defining lateral grooves on opposite sides thereof;   said circular openings being located on said front face and said oval openings being located on said back end;   said front face having a ball impacting sweet spot separating said circular openings;   said ball impacting sweet spot having a multiplicity of parallel spaced-apart slits extending between said circular openings;   a visual indicator disposed on said top surface adjacent to said front face and between said circular openings displaying the location of said ball impacting sweet spot;   said body opposite sides downwardly and inwardly sloping from the periphery of said top surface to the periphery of said undersurface to terminate with said side grooves; and   said body being of aerodynamic configuration having said top surface curved in a dome shape with said opposite sides sloping rearward from said front face to said back end in a curved manner to terminate with each of said oval openings respectively.
